In the January 13, 2009 blog study I looked at the concept of Turnaround Tuesdays. I found the old market adage really seemed to provide an edge. And while that edge had been prevalent since at least the 60’s, it had become even stronger over the last decade. Below I’ve rerun one of the tests from that post. In this case I looked for exactly 3 dwon days in a row and today being Monday.

These results are quite compelling and suggest a substantial upside edge.

Of course this morning’s huge gap down may throw a wrench into things. I examined similar gap situations on June 29, 2010.
